Putting feelings into words produces therapeutic effects in the brain

...an said. “Putting our feelings into words helps us heal better. If a friend is sad and we can get them to talk about it, that probably will make them feel better.” The right ventrolateral prefrontal cortex undergoes much of its development during a child’s preteen and teenage years.

Tissue engineered scaffolding allows reproduction of cartilage tissue

...f cartilage cells, which have a limited ability to heal naturally, to replace defective cartilage tissue. Cartilage cells are extracted and seeded to the scaffold which is implanted into the body, where new cartilage tissue is grown along the structure.

First demonstration of new hair follicle generation in an animal model

...with wnts or other proteins that allow the skin to heal in a way that has less scarring and includes all the normal structures of the skin, such as hair follicles and oil glands, rather than just a scar,?explains Cotsarelis. By introducing more wnt proteins to the wound, the researchers found that they...

Scientists see DNA get 'sunburned' for the first time

... DNA employs some chemical reactions of its own to heal itself. But when DNA sustains too much damage, it can't replicate properly. Badly damaged cells simply die -- the effect that gives sunburn its sting. Scientists also believe that chronic damage creates mutations that lead to diseases such as skin ca...

A team led by Philippe Collas at the University of Oslo in Norway has identified certain chemical marks that allow him to predict which, among the hundreds of millions of stem cells in liposuctioned fat, are best at regenerating...

Research project tackles 'regeneration' gap

But we can’t do things like grow an arm or finger as we did in the early stages of our development. We want to learn how to turn those systems back on in people." Recently, studies have shown humans...
